146512 ÷ 80 
We're looking to find how many times 80 goes into 146512.

Going ahead to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 80

On to step 2:
80 goes into 14 0 times with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 80

Let's proceed to step 3:
The number 80 fits into 146 1 times, leaving a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 80 from 146 leaves us with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 80

Moving on to step 4:
80 goes into 665 8 times with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 25 after subtracting 640 from 665.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 80

On to step 5:
80 goes into 251 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 183.0
Subtract 240 from 251 to get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 80

Going ahead to step 6:
When dividing 112 by 80, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1831.0
Subtract 80 from 112 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
320 divided by 80 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 1831.4
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1831.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1831.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1831.4 with a remainder of 0.0.
